Application filed. March 17, 1913. Serial No. 754,746.

To all whom it may concern Be it known that I, BENJAMIN G. PAT- rnnson, a citizen of the United States, and

- a resident of Oklahoma city, in the county a specification.

My inventlon 1s an improvement in enginestarters, and has for its object to provide mechanism of the character specified for connection with the engine shaft to permit the said shaft to be rotated by'the driver without dismounting, and from his usual seat, and wherein means is provided for disconnecting the said mechanlsm from the en gine shaft when the engine. is running.

In the drawings: Figure'l is a side view of a portion of an automobile provided with the improvement, Fig. 2 is a front view of the hood of the automobile with the attachment in place, Figs. 3 and 4: are similar views showing other arrangements for different mountings of engines, Fig. 5 is a plan view of the starting mechanism, Fig. 6 is a longitudinal vertical section of the shaft engaging means, Fig. 7 is a rear view of the sleeve, Fig. 8 is a section on the line '88 of Fig. 6, looking in the direction of the arrows, Fig. 9 isa section on the line 99 of Fig. 7, looking in the direction of the arrows, and Fig. 10 is a perspective view of the connecting means for thelever.

The present embodimentjof the invention is shown in connection with the engine of an automobile and the said mechanism comprises a lever 52, having one of its ends connected on a pair of lugs 3, on one of the arms 5 of an angle plate, whose other arm 6 is provided with a rectangular opening 7, and the said arm 5 of the angle plate is secured to a circular plate 8, the said plate having oppositely arranged arc-shaped slots 9, for receiving screws or bolts 10, to secure the said plate to the radiator of the automobile, at one side of the said radiator. The lever end passes through the opening 7 of the arm 6, and is connected to the lugs by end of the lever is received between spaced lugs 14 on the one end of a link 15, whose other end is pivoted at 16 to the lower end of a lever 17. The lever 17 is pivoted at 18 to the body of the automobile, adjacent to the driver, the upper end having a. grip 19, which is in position to grasp by the driver to operate the starting mechanism. The lever passes through an opening in the floor or bottom of the body, and a coil spring 20 has one of its 'ends connected with the lever below the pivot and the other end connected with a threaded rod 21, which passes through an opening in a bracket 22, secured to the body, and the rod is engaged by a'nut 23 on the opposite side of the bracket.

By means of the nut, the tension of the spring 20 may be varied to meet conditions, and the said spring normally holds the lever in the position of Fig. 1, that is, in such position that when the grip 1s moved rearwardly or toward the operator, the parts will be in position to start the engine. When the lever 17 is so moved, the end of the lever 2 remote from the plate 8 is moved away from the front of the radiator as shown in Fig. 5, the lever swinging on the link 11, and the movement of the lever is limited by the opening 7 of the arm 6 of the angle plate.

The lever 2 provided intermediate its ends with a lateral bend, forming one section 2st of a ring, the other section being formed by a clip 25, secured to the lever by means of bolts and nuts 26. The lateral bend and the clip form a circular ring at the center of the lever, and a sleeve 27 is connected to the ring, by means of trunnions or journal pins 28 and 29 on the sleeve and arranged at diametrical points, the said trunnions or journal pins passing through oppositely arranged openings 30 in the ring.

The outer end of the sleeve 27 is internally threaded as shown at 37, and a protector thimble or casing 31 has an annular externally threaded enlargement 32 at one end which is received within the sleeve as shown in Fig. 6. The outer end of the protector is closed as indicated at 33, and the said closure ispolygonalin cross section to receive a wrench or the like for permitting the removal of the protector. A sleeve nut 34 is arranged within the sleeve 27, the said sleeve nut having an annular marginal Patented May 12, 1914.

flange 35 at one end, which is received within a rabbet 38 in the inner end of the sleeve 27 and the opposite end of the sleeve nut has a ring 36 threaded thereon, the ring being received in a rabbet 39 at the opposite end of thesleeve 27.

The internally threaded portion 37 of the sleeve. 27 is within the rabbeted portion 39,; the threads being cut in .the said portion so that when the protector 31 is removed, access maybe had'to the ring 36 to remove the said ring to permit the removal of the sleeve nut34.' That portion of the internal surface of the sleeve nut between the rabbets 38 and 39 is provided with three grooves orrecesses 40, each of the said grooves having one of its walls inclined, and a roller 41 is arranged in each of the said grooves or recesses. The grooves or recesses 40 are so shaped that when the sleeve nut 34 is rotated in one direction, the rollers 41- will bind between the bottom wall of the re cess 40 and the periphery of the sleeve nut to prevent angular movement of the sleeve,

while when the nut is rotating in the opposite direction, the rollerswill roll into the deepest portion of the-recess 40 to prevent binding on the sleeve. I 7

The engine shaft 42 is provided on its periphery at the front endthereof with a plurality of spaced parallel spirally arranged grooves 43, and the inner surface of the sleeve nut 34 is provided with lugs 44, which .46 and w y will be evident that the rollers 40 and theengage the several grooves. When the thimble protector is in thenormal inoperative position shown in full lines in Fig.5, the outer end of the shaft is adjacent to the closed end of the protector, and the grooves 43 are of sufficient length to permit the shaft to occupythis position. The trunnion or journal pin '28 is provided with a vertical passage 45, and. the outer end of the passage is enlarged and internally threaded as indi cated at '46, forreceiving an oil cup 47. The oil cup is threaded into the enlargement en the cup is filled; with oil, it

external surface of the sleeve nut and the internal surface of the sleeve 27, will be thoroughly lubricated to eliminate friction.

In operation, the parts normally occupy the position in full lines in Figs. 1 and 5.

When the driver wishes to start the engine, he swings the u per end of the lever 17 toward the seat a ter arranging the fuel feed and igniting device in the proper position. This movement swings the lever into the dotted line position of Fig. 5, moving the" sleeve nut to the outer end of the engine shaft. The spring 20 is of suflicient strength to return the lever 17 to its original position as shown in Fig. 1, thus moving the sleeve nut toward the front of the automobile, that is, returning the parts to the full line position of Fig. 5. Since the clutch connection between the sleeve 27 and the nut 34 preventsrearward movement of the said nut with respect to the said-sleeve, the shaft 42 must be moved forwardly, thus turning over theengine 'and starting the same in a forwarddirection. The clutch connection between the nut 34 and the sleeve 27 permitsthe nuttorotate with respect to the sleeve, that is, permits'the nut to hold its relative position with respect to the engine shaft during the forward moving of the nut. When, however, the nut...,is moved I rearwardly, the rollers 41 move \into the shallow ortions of the grooves 'i 40 and firmly 100% the nut 34-to the sleeve 27. The position of the lever 2 will vary with different arrangements of engines as for instance, in the arrangement just described, the engine shaft is within the radiator, the said shaft extending through the front of the radiator near the lower edge thereof. In the construction of Fig. 3 the engine shaft is below the radiator 48 and in this arrangement the plate 8 is secured to abracket 49, depending from the radiator. .In the construction shown in Fig. 4, the engine shaft is above the frame 50 of the radiator, being arranged in the radiating part 51 thereof. With this construction the plate 8 is secured to the radiator at a higher point than in the construction of Fig. 2.. What ever the level of the engine shaft, the lever 2 is so arranged thatthat end thereof which is connected to the link 15 is at the lower-left corner of the radiator, so that the operating lever. 17 will be adjacent to the right hand of the driver. The connect-. ing member shown in Fig. 10 permits this connection as clearly shown in- Figs. 2 to 4 inclusive; 7 By loosening the nuts 10, the plate 8 may be turned 'annularly to the proper position to bring the. movable. ends of the ,lever 2 at the point desired.
